LCM of 35 and 55 by Prime Factorization

Prime factorization of 35 and 55 is (5 × 7) = 5¹ × 7¹ and (5 × 11) = 5¹ × 11¹ respectively. LCM of 35 and 55 can be obtained by multiplying prime factors raised to their respective highest power, i.e. 5¹ × 7¹ × 11¹ = 385.
Hence, the LCM of 35 and 55 by prime factorization is 385.

LCM of 35 and 55 by Division Method

To calculate the LCM of 35 and 55 by the division method, we will divide the numbers(35, 55) by their prime factors (preferably common). The product of these divisors gives the LCM of 35 and 55.

• Step 1: Find the smallest prime number that is a factor of at least one of the numbers, 35 and 55. Write this prime number(5) on the left of the given numbers(35 and 55), separated as per the ladder arrangement.
• Step 2: If any of the given numbers (35, 55) is a multiple of 5, divide it by 5 and write the quotient below it. Bring down any number that is not divisible by the prime number.
• Step 3: Continue the steps until only 1s are left in the last row.

The LCM of 35 and 55 is the product of all prime numbers on the left, i.e. LCM(35, 55) by division method = 5 × 7 × 11 = 385.

LCM of 35 and 55 by Listing Multiples
